d5f8f38ac6 tailcfg: rename map request version to "capability version" 
And add a CapabilityVersion type, primarily for documentation.

This makes MapRequest.Version, RegisterRequest.Version, and
SetDNSRequest.Version all use the same version, which will avoid
confusing in the future if Register or SetDNS ever changed their
semantics on Version change. (Currently they're both always 1)

This will requre a control server change to allow a
SetDNSRequest.Version value other than 1 to be deployed first.

5d085a6f41 controlhttp: add some docs, change Dial's path from /switch to /ts2021 
When I deployed server-side changes, I put the upgrade handler at /ts2021
instead of /switch. We could move the server to /switch, but ts2021 seems
more specific and better, but I don't feel strongly.

8c3c5e80b7 tailcfg: make MapResponse.ControlTime a pointer 
Otherwise omitempty doesn't work.

This is wire-compatible with a non-pointer type, so switching
is safe, now and in the future.

3a94ece30c control/controlclient: remove dummy endpoint in endpoint stripping mode 
The TODO is done. Magicsock doesn't require any endpoints to create an
*endpoint now.  Verified both in code and empirically: I can use the
env knob and access everything.

adda2d2a51 control/controlclient: select newer certificate

issued the most recently (as determined by the NotBefore timestamp).
This also adds some tests for the function that performs that

d5a7eabcd0 control/controlbase: enable asynchronous client handshaking. 
With this change, the client can obtain the initial handshake message
separately from the rest of the handshake, for embedding into another
protocol. This enables things like RTT reduction by stuffing the
handshake initiation message into an HTTP header.

Similarly, the server API optionally accepts a pre-read Noise initiation
message, in addition to reading the message directly off a net.Conn.
